Abstract

Apparatus and associated methods relate to providing an optical display apparatus that can be used to make a light source display variable apparent sizes in response to light intensities emitted by the light source. In an illustrative example, the optical display apparatus may have a first baffle arranged on the top of a light source. The optical display apparatus may also include a second baffle, the first baffle may be nested in the second baffle such that a first intensity of a first beam of light guided within the first baffle is stronger than a second intensity of the second beam of light guided between the first baffle and the second baffle. By adjusting the light intensities, different display regions of a translucent diffuser may be lit, which may provide controllable apparent sizes of a light structure.
